Callinan sets Record and Meeting Dates for Spin-Out Transaction

VANCOUVER, March 25 /CNW/ -Callinan Mines Limited (TSXV: CAA) (OTCBB: CCNMF) announces that the Board of Directors has set the date for the special meeting (the "Meeting") of Callinan shareholders to consider the spin-out transaction (the "Transaction") previously announced on October 25, 2010. The Board has set June 7, 2011 as the date for the Meeting and April 28, 2011 as the record date for the Meeting. A complete description of the Transaction will be set forth in a management information circular to be sent to Callinan's shareholders in connection with the Meeting.

The Transaction is intended to provide Callinan shareholders with the opportunity to continue to participate in both aspects of Callinan's present holdings. Pursuant to the Transaction, Callinan's exploration assets, including Callinan's interest in the Coles Creek polymetallic project in British Columbia, and the Gossan Hill gold and silver Project in Manitoba, will be transferred to a new corporation ("Newco"). Following the implementation of the Transaction, which will be accomplished through a plan of arrangement, the shareholders will hold shares in two corporations, existing Callinan and Newco. Existing Callinan shareholders will receive the same percentage interest in Newco as they presently hold in Callinan. Callinan will continue to hold a 6&#8532;% Net Profits Interest royalty and a $0.25 per ton royalty in the 777 Mine at Flin Flon, Manitoba, Canada, which produces copper, gold, zinc and silver and is operated by HudBay Minerals Inc., as well as the War Baby mineral property.

The implementation of the Transaction is subject to, among other things, further Board and shareholder approval of the final structure and terms and the arrangement agreement to be entered into with Newco. The Transaction is also subject to Court approval and other regulatory approvals, including TSX Venture Exchange ("Exchange") acceptance of the Transaction and the continued listing of Callinan common shares on the Exchange and conditional listing approval of Newco shares. No application for listing has been made and there is no assurance that approval will be granted.

On Behalf of the Board of Directors,

Mike Muzylowski
